RGB or Red, Green Blue tells the display device definitively what color to display. The 2 work differently so developers can use either method depending on the desired result.
RGB values are from 0-255. When combined can create other over 62,000 different colors you can see.
Hexcode is machine language that contains 3 sets of (2) numbers that range from 0-15. With letters representing 2 digit numbers. (Example" "A" = 10, "B"=11, C"=12, "D"=13", "E"=14, "F"=15.
These colors will not dither on any 256 color Windows or Mac monitors. Netscape Communicator 4.0 uses a different palette for Macs - 256 color Mac monitors will dither to a different palette. Unix monitors use a different palette. In other words, colors may appear different on different operating systems.
For the developer it is nice to get a visual refference when laying out a page, graphic art or element in a page. Use this color chart to see conversions from hex code to RGB values.
While it is not possible to chart every possible color the ones in this color chart are the most commonly used. Use this chart to select colors for your next design. Check for mix, match and complimentary colors at a glance.
